In need of something positive

Okay so I posted yesterday saying how scared I was to try again. I miscarried August 11th. Or maybe a few days sooner. We knew for sure on that date. Any who. I took three tests today. All positive . I want to be excited but I can only feel scared. I don't want to go through another miscarriage especially this soon. We only had sex maybe twice after the loss and then I shut down and told my SO we needed to wait. Is it possible that this pregnancy can make it or did I just set my self up for another painful experience.?
